To investigate the changes in match demands of Australian Football League Women's (AFLW) athletes over the past 3 seasons (2022-2023). It was hypothesized that match demands would increase across all positional groups.
Forty-two athletes from 1 AFLW club who played at least 1 match across seasons 6 to 8 (2022-2023) were included. Match-day running demands including total distance (TD), speed, acceleration, high-intensity running (HIR; >19 km/h), very HIR (VHIR; >21 km/h), and sprint distances (>24 km/h) were exported from Catapult Vector S7 global positioning system units. Raw speed (in meters per minute) and acceleration (in meters per second squared) files were exported to calculate 1-minute rolling peak periods. Linear mixed-effects regression models were conducted with effect sizes (d) to examine changes in match demands over time for the cohort and playing-position groups.
TD increased by 344 m (d = 0.33) between seasons 6 and 7 and 971 m (d = 0.72) between seasons 7 and 8 (P < .001). HIR, VHIR, rolling 1-minute peak speed, and acceleration increased between seasons 6 and 7 by 70 m (d = 0.38), 36 m (d = 0.31), 5.1 m/min (d = 0.15), and 0.04 m/s2 (d = 0.46), respectively (P < .001), while no changes were seen between seasons 7 and 8. Total player load increased by 28 AU (d = 0.29) between seasons 6 and 7 and 80 AU (d = 0.54) between seasons 7 and 8 (P < .001).
TD increased across seasons 6 to 8, whereas HIR, VHIR, rolling 1-minute peak speed, and acceleration only increased between seasons 6 and 7. While changes in TD may encompass factors such as rule changes, relative metrics including HIR and VHIR changed in this cohort. These findings provide a comprehensive evaluation of current AFLW match demands and will assist in future AFLW athlete preparation.
调查澳大利亚女子足球联盟（AFLW）运动员在过去三个赛季（2022 - 2023年）比赛需求的变化。研究假设是所有位置组的比赛需求都会增加。
纳入了来自1个AFLW俱乐部的42名运动员，他们在第6至8赛季（2022 - 2023年）至少参加了1场比赛。比赛日的跑步需求，包括总距离（TD）、速度、加速度、高强度跑步（HIR；>19公里/小时）、极高强度跑步（VHIR；>21公里/小时）和冲刺距离（>24公里/小时），从弹射向量S7全球定位系统单元导出。导出原始速度（以米/分钟为单位）和加速度（以米/秒²为单位）文件以计算1分钟滚动峰值时段。使用效应量（d）进行线性混合效应回归模型，以检查该队列和比赛位置组随时间的比赛需求变化。
TD在第6和第7赛季之间增加了344米（d = 0.33），在第7和第8赛季之间增加了971米（d = 0.72）（P <.001）。HIR、VHIR、1分钟滚动峰值速度和加速度在第6和第7赛季之间分别增加了70米（d = 0.38）、36米（d = 0.31）、5.1米/分钟（d = 0.15）和0.04米/秒²（d = 0.46）（P <.001），而在第
